Hi there. In most cases, yes. Paywalls segregate customers who have the entitlement for a specific feature based on status, packaging, revenue or some other distinction and you would keep the flag in place permanently to manage the users based on an attribute or being in a whitelist.

There are cases where premium users get early access, but eventually the feature is made available to all users. In that case you'd retire the flag once the feature is no longer restricted.
